Here's a pic of my 91 Sentra. I just got her out of the shop last week, but I still need to get additional work done to get it running in smooth (something's wrong with the right front brake, and I need to get a smog and have it registered). This pic is somewhat deceiving as it just rained and I noticed how nice the car looked, so I took a picture. Doesn't look that bad for a 17+ y.o. car, however, once it dried, you could see the hard water stains and the faded color from sitting outside for 9 years. I'm still on the fence whether or not I should stick with the red color, or go with a two-tone.

Here's a photoshop of what I'm envisioning it would look like two-tone (I'd add a silver pin stripe separating the two colors, but it didn't look so hot in PS):
